Title: Ulrik Petersen Emdros Database Engine MQL Parsing Denial Of Service Vulnerability
Severity: MODERATE
Description:
Emdros is a text database engine designed for annotated or analyzed text. It supports MQL, a query language designed to provide information about text.
A denial of service vulnerability affects Emdros. This issue is due to a failure of the application to properly manage memory.
The problem presents itself when the affected application attempts to parse excessively long, malformed MQL queries. Apparently, in various situations, the affected application will leak memory during the parsing process, eventually leading to excessive memory consumption and ultimately a denial of service condition.
Apparently this issue is distinct from that reported in BID 11143 (Ulrik Petersen Emdros Database Engine Denial Of Service Vulnerability). It should also be noted that if the affected application is run as a daemon, a remote attacker could exploit this issue.
An attacker may leverage this issue to cause the affected application to crash, denying service to legitimate users.
